Two road salt-related questions
Does anyone here wash the underside of cars? How?
Is there a decent place in Chicagoland where one can have the underside rinsed?

You can always jack it up on all fours or somehow get it on a lift and spray away with some scrubbing.
To reduce getting salt, sand and sh*t into the car I turn sideways and sit down w/ my feet outside of the car, and click my heels and soles together several times before putting them inside. That helps a lot.
Happy winter driving!

Is there a place in Chicago with high pressure wash? What is QEW?
Thanks for the tip re entering the car.
It is truly a wonder product: One 32 oz. bottle of Quick & Easy Wash does 32 car washes. You can wash anywhere without rinsing; where water use is restricted such as campgrounds, storage facilities, apartment parking stalls, airplane tiedowns, marinas and even in your garage.
They are having a 2 for 1 sale of QEW. Check out their Website @ http://www.protectall.com/qe.aspx
If you really want to know about QEW, go the the Website of pro detailers @ http://autopia.org/forum/ and do a search on it.
I love this stuff! It seems too good to be true, but this is one that is very good.

Also, I don't know about the E55, but I know my CLK500 has plastic covering the bottom of the car so I dont think salt is a big problem for the undercarraige. If that's the case with your car, you can get away with only having the rocker panels and wheel wells washed very well. If your dealer does it for free I'd just ask them to do that for you.
I will look for the Skokie Blvd. Turtle Wax place. Thanks.
A: Use a stiff brush to dislodge any loose road salt and then remove with a vacuum, spray the area with a carpet cleaner and let it soak in, the salt stains are alkaline in nature, so I'd reach for an acidic product to counteract/neutralize. You might find that rinsing with a solution of white vinegar /water helps. Repeat until most of the stain has been lifted. Finally clean carpets by spraying the area with a carpet shampoo rinse and then remove with a carpet extractor. Using the vacuum, remove the excess moisture, loose dirt and the grime, allow carpets / mats to thoroughly dry before use, and then apply a fabric protection (303TM High Tech Fabric Guard) Be aware that once you add water to salt it becomes corrosive, so take care to dry the affected area thoroughly after the salt has been removed.
Q: Does anyone here wash the underside of cars? How?
A: The salts (often mixed with grit / sand for tyre adhesion) commonly used are;
(a) Sodium chloride (NaCl) the most common salt used
(b) Calcium chloride (CaCl2) works at lower temperatures than sodium
chloride.
Although salt is inert when subjected to freezing (15 - 20oF ) it’s considered the lower limit for salt to melt snow/ice but once H2O, even in the form of moist air (i.e. humidity) is added the freezing point is lowered and the saline solution(salt/water) will have an adverse effect on the vehicles paint and undercarriage.
When washing the vehicle ensure that all salt is removed to avoid a saline solution remaining on the paint finish. Using a durable protection (Collinite Insulator Wax) will provide a sacrificial and renewable protection to the vehicles paint finish.
Magnesium chloride (MgCl2) is very effective even at the lowest temperatures but also contains the most aggressive corrosives (especially on glass surfaces) and (d) a sprayed brine solution, it is used to prevent snow / ice adhesion to the road surface. Needless to state that all these salts are acidic / corrosive so once you've removed the ice / snow it may be advisable to 'neutralize ' the residue road salt with an alkaline solution, (Canada-POR15.com) especially from the undercarriage and suspension:
Methodology
•Thoroughly spray an undiluted citrus cleaner (P2IS Total Auto Wash) allow the solution to dwell for ten to fifteen minutes and remove by thoroughly rinsing with water.
•If you have a pressure washer available, fill tank with citrus cleaner and spray undercarriage (do not use excess pressure as water may penetrate crevices and seams where it cannot drain, causing corrosion), let it soak and then remove with plain water
•Spray undercarriage with (POR-15 Marine Clean™) one application will leave no residues, noxious fumes or flammable solvents (Canada-POR15.com)
•Apply two coats (allowing first coat to dry) of a rust inhibitor paint (POR-15 Rust Inhibitor, allow drying (3-6 hours) between coats.
An extraction system process is the choice of professional detailers due to its cost effectiveness, performance efficiency and time saving over conventional methods. Extractors work by using a cleaning solution dispensed from a tank that heats the solution to 200oF+ and is sprayed at medium pressure, high volume from the machine via a cleaning wand; it is then filtered and re-circulated.
Extraction also allows the ability to remove cleaning residues due to its high suction power (100-inch water gauge +). Rinsed fabrics look and smell cleaner and resist soiling better.
